**Characteristic function (probability theory)**— The characteristic function of a uniform U(–1,1) random variable. This function is real valued because it corresponds to a random variable that is symmetric around the origin; however in general case characteristic functions may be complex valued …71

**Characteristic polynomial**— This article is about the characteristic polynomial of a matrix. For the characteristic polynomial of a matroid, see Matroid. For that of a graded poset, see Graded poset. In linear algebra, one associates a polynomial to every square matrix: its …72

**Characteristic subgroup**— In mathematics, particularly in the area of abstract algebra known as group theory, a characteristic subgroup is a subgroup that is invariant under all automorphisms of the parent group.[1][2] Because conjugation is an automorphism, every… …73

**Characteristic class**— In mathematics, a characteristic class is a way of associating to each principal bundle on a topological space X a cohomology class of X. The cohomology class measures the extent to which the bundle is twisted particularly, whether it possesses… …74

**Characteristic (algebra)**— In mathematics, the characteristic of a ring R, often denoted char(R), is defined to be the smallest number of times one must use the ring s multiplicative identity element (1) in a sum to get the additive identity element (0); the ring is said… …75

**Characteristic set**— The mathematical concept of a characteristic set was discovered in the late forties by J.F. Ritt. Besides Gröbner basis method, it provides an alternative algorithmic way for solving multivariate polynomial equations or differential equations.In… …76

**Characteristic based product configurator**— A characteristic based product configurator is a product configurator extension which uses a set of discrete variables, called characteristics (or features), to define all the possible product variations. The characteristics There are two… …79

**Characteristic state function**— The characteristic state function in statistical mechanics refers to a particular relationship between the partition function of an ensemble. In particular, if the partition function P satisfies P = exp( − βQ) or P = exp( + βQ) in which Q is a… …80

**Characteristic exponent**— In mathematics, the term characteristic exponent may refer to: Characteristic exponent of a field, a number equal to 1 if the field has characteristic 0, and equal to p if the field has characteristic p > 0 Lyapunov characteristic exponent, a… …
